Configuring Availability Manually

1. On the wireless controller Availability screen, set up the controller in Paired Mode.
2. On the VNS configuration window, define a VNS (through topology, WLAN service, role and VNS configuration) on each controller with the same SSID. The IP addresses must be unique. For more information, see Manually Creating a VNS. A controller VLAN Bridged topology can permit two controllers to share the same subnet. This setup provides support for mobility users in a VLAN Bridged VNS.
3. On both controllers, on the AP Registration screen, select the Security Mode Allow only approved APs to connect option so that no more APs can register unless they are approved by the administrator.
4. On each controller, on the AP configuration Access Approval screen, check the status of the APs and approve any APs that should be connected to that controller.

   System AP defaults can be used to assign a group of VNSs to the foreign APs:

   • If the APs are not yet known to the system, the AP will be initially configured according to AP default settings. To ensure better transition in availability, Extreme Networks recommends that the AP default settings match the desired assignment for failover APs.
   • AP assignment to WLAN Services according to the AP default settings can be overwritten by manually modifying the AP assignment. (For example, select and assign each WLAN service that the AP should connect to.)
   • If specific foreign APs have been assigned to a WLAN service, those specific foreign AP assignments are used.
